Getting Started

Running with Docker

OvenMediaEngine supports the Docker image from AirenSoft's Docker Hub (airensoft/ovenmediaengine) repository. After installing Docker, you can simply run the following command:
1
docker run -d \
2
-p 1935:1935 -p 4000-4005:4000-4005/udp -p 3333:3333 -p 8080:8080 -p 9000:9000 -p 10000-10005:10000-10005/udp \

Manual Installation and Execution

Install dependencies

OvenMediaEngine can work with a variety of open-sources and libraries. First, install them on your clean Linux machine as described below. We think that OME can support most Linux packages, but the tested platforms we use are Ubuntu 18+, Fedora 28+, and CentOS 7+.
1
(curl -LOJ https://github.com/AirenSoft/OvenMediaEngine/archive/v0.10.4.tar.gz && tar xvfz OvenMediaEngine-0.10.4.tar.gz)
2
OvenMediaEngine-0.10.4/misc/prerequisites.sh
Copied!
If the prerequisites.sh script fails, proceed with the manual installation.

Build & Run

You can build the OvenMediaEngine source using the following command:
Ubuntu 18
Fedora 28
CentOS 7
1
sudo apt-get update
2
cd OvenMediaEngine-0.10.4/src
3
make release
4
sudo make install
5
systemctl start ovenmediaengine
6
# If you want automatically start on boot
7
systemctl enable ovenmediaengine.service 
Copied!
1
sudo dnf update
2
cd OvenMediaEngine-0.10.4/src
3
make release
4
sudo make install
5
systemctl start ovenmediaengine
6
# If you want automatically start on boot
7
systemctl enable ovenmediaengine.service
Copied!
1
sudo yum update
2
source scl_source enable devtoolset-7
3
cd OvenMediaEngine-0.10.4/src
4
make release
5
sudo make install
6
systemctl start ovenmediaengine
7
# If you want automatically start on boot
8
systemctl enable ovenmediaengine.service
Copied!
In addition, we recommend that you permanently set environment variables as follows.
1
$ echo 'source scl_source enable devtoolset-7' >> ~/.bashrc
Copied!
if systemctl start ovenmediaengine fails in Fedora, SELinux may be the cause. See Check SELinux section of Troubleshooting.

Ports used by default

The default configuration uses the following ports, so you need to open it in your firewall settings.
Port
Purpose
1935/TCP
RTMP Input
4000-4005/UDP
MPEG-2 TS Input
9000/TCP
Origin Server (OVT)
80/TCP
HLS & MPEG-Dash Streaming
3333/TCP
WebRTC Signalling
10000 - 10005/UDP
WebRTC Ice candidate
You can open firewall ports as in the following example:
1
$ sudo firewall-cmd --add-port=80/tcp
2
$ sudo firewall-cmd --add-port=1935/tcp
3
$ sudo firewall-cmd --add-port=4000-4005/udp
4
$ sudo firewall-cmd --add-port=3333/tcp
5
$ sudo firewall-cmd --add-port=9000/tcp
6
$ sudo firewall-cmd --add-port=10000-10005/udp

Hello Sub-Second Latency Streaming

Start Streaming

You can live streaming using live encoders such as OBS, XSplit, and OvenStreamEncoder. Please set the RTMP URL as below:
rtmp://<Server IP>[:<RTMP Port>]/<Application name>/<Stream name>
The meanings of each item are as follows:
  • <Server IP>: IP address or domain of the OvenMediaEngine server.
  • <RTMP Port>: You can use <Port> of <Provider> in the above Server.xml file. With the default configuration, the RTMP default port (1935) is used. Also, by setting the default port, you can omit the port.
  • <Application name>: This value corresponds to <Name> of <Application> in conf/Server.xml. If you use the default configuration, you can use the app.
  • <Stream name>: Name of the stream you defined.
After you enter the above RTMP URL into the encoder and start publishing, you will have an environment in which the player can view the live stream.

Example of using OBS Encoder

The server address in OBS needs to use <Application name> generated in Server.xml. If you use the default configuration, the app is already created and ready to use.
  • Install OBS on your PC and run it.
  • Click "File" in the top menu, then click "Settings" (or press "Settings" on the lower right).
  • Select the "Stream" tab and enter your stream information.
Press "Service" and select "Custom", your OBS is the same as this image.
  • Go to the "Output" tab.
  • Set the following entries.
For lower latency, we recommend using the Hardware Encoder as follows: "NVENC" provides a Low-Latency preset. It's also important to set "MAX B-frame = 0" to reduce latency.
If Hardware Encoder isn't installed on your PC, it's recommended to set x264 as follows: We highly recommend setting "bframes = 0" to reduce latency. Then set the "threads" option to 8 or less. Chrome doesn't handle more than 10 Nal Units. The best way to avoid this is to set "thread = 8".
We recommend checking "Enable new networking code" and "Low latency mode" on Network in Advanced Settings as follows:

Play

We have prepared a test player so that you can easily check if OvenMediaEngine is working properly. Please see the chapter on Test Player for more information.
Please note that WebRTC Signalling URL is similar to the RTMP URL and consists of the following:
  • ws://<Server IP>:[<Signalling Port>/<Application name>/<Output Stream name>
    • <Server IP>: IP address or domain of the OvenMediaEngine server.
    • <Signalling Port>: You can use the value of <Signalling><ListenPort> in Server.xml above. If you use the default configuration, the WebRTC Signalling default port (3333) is used.
    • <Application name>: This value corresponds to <Name> of <Application> in conf/Server.xml. If you use the default configuration, you can use the app.
    • <Output Stream name>: You have to use an output stream name for streaming. If you use the default configuration, an output stream named <Stream Name> is automatically generated when the stream is input.
As of version 0.10.4, the default output stream name has been changed from <Input Stream Name>_o to <Input Stream Name>, and has been updated to use the input stream name as the output stream name for convenience.
If you use the default configuration, the RTMP publishing URL is rtmp://192.168.0.1:1935/app/stream
Then the WebRTC URL will bews://192.168.0.1:3333/app/stream
In addition,
HLS streaming URL will behttp://192.168.0.1:8080/app/stream/playlist.m3u8
MPEG-DASH streaming URL will behttp://192.168.0.1:8080/app/stream/manifest.mpd
Low-Latency MPEG-DASH streaming URL will be http://192.168.0.1:8080/app/stream/manifest_ll.mpd
